Definitions:

π Electrons

Electrons present in the pi bonds of a molecule which contribute to the molecule's chemical properties.

Aromatic

Refers to a class of compounds that contain a benzene ring or a similar structure with delocalized electrons that follow Huckel's rule.

AntiAromatic

Compounds that have conjugated pi electron systems with 4n pi electrons, which destabilize the molecule, making it less stable than if the pi electrons were localized.

NonAromatic

Refers to organic compounds that do not possess the special stability associated with cyclic, planar systems that follow Huckel’s rule of delocalized electrons.
